ABSTRACT:
Each pixel of a solid state imaging element includes a photodiode, a field effect transistor (FET) having a gate connected to an output of the photodiode, a first feedback circuit connecting the gate and drain of the FET with a first switch inserted in series in a middle thereof, a second feedback circuit connecting the gate and drain of the FET with a second switch and a first capacitor in series in a middle thereof, and a second capacitor connected between a middle of the first capacitor and the second switch and an electric potential. A charge detector includes a capacitor, an amplifier having a negative input connected to the capacitor, a reset switch connected in a feedback circuit connecting an output of the amplifier and the negative input of the amplifier, and at least one circuit connected in parallel with the feedback circuit and having an additional reset switch connecting an output of the amplifier and the negative input of the amplifier and an additional capacitor.
